Each time I use my heat or A/C...I can smell the exhaust :squint:
I know there is one gasket I need to replace which is probably causing this (the gasket by the header and the block). But there must be another one that I can't find...
When it's raining out or there's any significant amount of water/puddles, somehow water gets INTO my exhaust pipe and makes this scratchy noise as it runs through the length of the pipe

I can't find another leak and I don't know where else to look.
Any suggestions? :thinking:
